4 + (2/3)/7 = 4 + 2/21 = 84/21 + 2/21 = 86/21 or 4 2/21
but maybe you really meant to write
(4+ 2/3)/ 7 = (14/3)/7 = 14/21 = 2/3
while I suspect; you want 2/3 as the answer
the order of operations PEMDAS puts division D before addition A. so the "and" would go last
You would have to divide 2/3 by 7 first, than add the result to 4. That's technically how you should solve this. But this problem may be ambiguous, given the English language reading from left to right as the order, and the problem really intended to add before dividing. The English language doesn't often capture mathematical technicalities.
I'd go with 2/3 as the answer
PEMDAS stands for
P: Parentheses. Do whatever is inside parentheses first, if any
E: Exponents. Do exponents next, if any
M: Multiplication next, if any
D: Division next if any
A: Addition next if any
S: Subtraction last, if any
In this problem all you had was A and D. D comes first
